Constructor Details

#initialize(input, properties = {}) ⇒ CaptureEndEngine

Initializes the engine. Accepts the same arguments as ::Erubi::Engine, and these additional options:

:escape_capture

Whether to make <%|= escape by default, and <%|== not escape by default, defaults to the same value as :escape.

:yield_returns_buffer

Whether to have <%| tags insert the buffer as an expression, so that <%| end %> tags will have the buffer be the last expression inside the block, and therefore have the buffer be returned by the yield expression. Normally the buffer will be returned anyway, but there are cases where the last expression will not be the buffer, and therefore a different object will be returned.
